一、灵感学习任何算法,最重要的点就是掌握算法的核心本质。本文重点介绍两种经典算法(DP和GA)的差异和相同点。 二、DP和GA的异同点2.1 、相同点:DP和GA都利用了历史信息进行求解。但是二者利用历史信息的方式…
There is a confusing question, i.e. the name of this method is dynamic programming, how can we understand it ? The dynamic programming in chinese is “动态规划”, to be honest, this translation is imprecise, because we can’t get the real thinking of the this algorithm. The programming ...

In the application of solving the backpack problem, greedy algorithm is faster, but the resulting solution is not always optimal; dynamic programming results in an optimal solution, but the solving speed is slower. The research compares the application properties and application scope of the two ...
When facing a mathematical problem, there may be several ways to design a solution. We can implement an iterative solution, or some advanced techniques, such as divide and conquer principle (e.g.Quicksort algorithm) or approach with dynamic programming (e.g.Knapsack problem) and many more. ...

TL;DR: This is an informal summary of our recent paper On the Unreasonable Effectiveness of the Greedy Algorithm: Greedy Adapts to Sharpness with Mohit Singh, and Alfredo Torrico, where we adapt the sharpness concept from convex optimization to explain t
In this paper, we introduce a model of task scheduling for a cloud-computing data center to analyze energy-efficient task scheduling. We formulate the assignments of tasks to servers as an integer-programming problem with the objective of minimizing the
